Some parents may notice their child making a grinding or squeaking sound with their teeth, especially during sleep, which can raise concerns and questions:
Is this normal? Does it cause harm? And what can be done about it?

In this article, we explain the causes of teeth grinding in children, when it becomes a concern, and how to handle it properly.

What is Teeth Grinding in Children?

Teeth grinding, or bruxism, is the repeated clenching or grinding of the upper and lower teeth, either while awake or during sleep.
It’s most commonly observed in children between the ages of 3 and 7. It may be temporary and disappear over time, or it could persist and require intervention.

What Causes Teeth Grinding in Children?

Stress or Anxiety

A child experiencing emotional stress or life changes (such as starting a new school or the arrival of a new sibling) may express tension through teeth grinding.

Temporary Physical Pain

Pain from teething, ear infections, or a toothache may cause a child to grind their teeth as a way to relieve discomfort.

Poor Dental Alignment

In some cases, misaligned teeth or jaw issues may lead to unconscious grinding.

Irregular Sleep Patterns

Lack of sleep or disrupted sleep can increase the likelihood of nighttime grinding.

Behavioral or Neurological Factors

Teeth grinding may also be seen in children with ADHD or certain developmental disorders.

Is Teeth Grinding Harmful?

In most cases, bruxism is temporary and does not cause permanent damage.
However, if it persists, it may lead to:

• Wearing down of tooth enamel
• Headaches or jaw pain
• Temporomandibular joint (TMJ) problems
• Sleep disturbances

When Should You See a Doctor?

• If the grinding sound is constant and affects the child’s or others’ sleep
• If you notice visible tooth wear
• If the child complains of jaw or head pain upon waking
• If the child exhibits signs of anxiety or neurological issues

How to Manage the Problem

Talk to Your Child Gently

Ask if anything is bothering them and watch for signs of stress or anxiety.

Create a Calm Sleep Environment

Establish a relaxing bedtime routine, such as reading a story or playing soft music.

Consult a Dentist

Have a dental check-up to identify any physical causes. The dentist may recommend a night guard if necessary.

Seek Psychological Support (if needed)

If grinding is linked to anxiety or stress, behavioral therapy can be helpful.

Summary

Teeth grinding in children is common at certain developmental stages and is often temporary.
However, by paying attention to both psychological and physical causes, and consulting professionals when needed, the issue can be effectively managed and resolved.
